<div class="textblock"><p>All Points Addressable (APA) mode drawing library.</p>
<p>Drawing routines originally by Pascal Felber Legendary overhall by Jon Fuge : <a href="https://github.com/jf1452">https://github.com/jf1452</a> Commenting by Michael Hope</p>
<p>Note: The standard text <a class="el" href="stdio_8h.html#a133c04c35a1c14c6f8d8078831705661">printf()</a> and <a class="el" href="stdio_8h.html#aab41487f7727cf7eb7377f9b8f494c58">putchar()</a> cannot be used in APA mode - use <a class="el" href="drawing_8h.html#a5f7a0ed309f9526e9be285146559848c">gprintf()</a> and <a class="el" href="drawing_8h.html#a9178e678a17cb08653600f435093ae2a">wrtchr()</a> instead.</p>
<p>Note: Using drawing.h will cause it's custom VBL and LCD ISRs (<code>drawing_vbl</code> and <code>drawing_lcd</code>) to be installed. Changing the mode (<code>mode(M_TEXT_OUT);</code>) will cause them to be de-installed.</p>
<p>The valid coordinate ranges are from (x,y) 0,0 to 159,143. There is no built-in clipping, so drawing outside valid coordinates will likely produce undesired results (wrapping/etc).</p>
<hr  />
<p><b>Important note for the drawing API :</b></p>
<p>The Game Boy graphics hardware is not well suited to frame-buffer style graphics such as the kind provided in <code>drawing.h</code>. Due to that, <b>most drawing functions (rectangles, circles, etc) will be slow</b> . When possible it's much faster and more efficient to work with the tiles and tile maps that the Game Boy hardware is built around. </p>
